meta-avs-demos Yocto layer meta-avs-demos is a Yocto meta layer (complementary to the NXP BSP release for i.MX) published on CodeAurora that includes the additional required packages to support Amazon's Alexa Voice Services SDK (AVS_SDK) applications. The build procedure is the described on the README.md of the corresponding branch. We have 2 fuctional branches now: imx-alexa-sdk: Support for Morty based i.mx releases imx7d-pico-avs-sdk_4.1.15-1.0.0: legacy support for Jethro releases The master branch is only used to collect manifest files, that used with repo init/sync commands will fetch the whole environment for the 2 special supported boards: i.MX7D Pico Pi and i.MX8M EVK. However the meta-avs-demos can be used with any i.MX board either. Recipes to include Amazon's Alexa Voice Services in your applications. The meta-avs-demos provides the required recipes to build an i.MX image with the support for running Alexa SDK. The imx-alexa-sdk branch is based on Morty and kernel 4.9.X and it supports the next builds: i.MX7D Pico Pi i.MX8M EVK Generic i.MX board For the i.MX7D Pico Pi and i.MX8M EVK there is an extended support for additional (external) Sound Cards like: TechNexion VoiceHat: 2Mic Array board with DSPConcepts SW support Synaptics Card: 2 Mic with Sensory WakeWord support The Generic i.MX is for any other regular i.MX board supported on the official NXP BSP releases. Only the default soundcard (embedded) on the board is supported. Sensory wakeword is currently only enabled for those with ARMV7 architecture. To support any external board like the VoiceHat or Synaptics is up to the user to include the additional patches/changes required.
